Methods and Systems For Providing Variable Mechanical Brake Torque
First Claim
1. A method for controlling a rotational speed of a drivetrain for a wind turbine, the drivetrain coupled to a rotor shaft and a generator rotor shaft, said method comprising:
- operatively coupling a mechanical brake to the drivetrain, the mechanical brake including a brake caliper and a brake disc coupled to the drivetrain;
actuating the brake caliper to apply a braking force on the brake disc, wherein the braking force generates a brake torque exerted by the brake system;
detecting a parameter of the wind turbine;
determining an operating command based on the parameter; and
,controlling the mechanical brake based on the operating command, wherein the operating command selectively adjusts the brake torque exerted by the brake system.
